System, apparatus, and/or a method for checking hardware components in an information handling system is disclosed that includes selecting a hardware component for testing; supplying power to the hardware component independent from the power supply provided by the information handling system; performing testing on the selected hardware component using power supplied by the independent power supply; determining the success or failure of the testing on the selected hardware component; indicating the result of the testing on the selected hardware component; and if the result of the testing on the selected hardware component is successful indicate the hardware component passed the testing, and if the result of the testing on the selected hardware component is not successful re-seat the hardware component and perform the testing on the selected hardware again.

System and method for hardware component connectivity verification

A circuit board and method of manufacture therefor utilize voltage domain edge plating disposed on at least a portion of one or more edges of a circuit board to electrically couple voltage domain conductive shapes disposed in different conductive layers of the circuit board. By doing so, interconnection of multiple voltage domain conductive shapes in different conductive layers may be facilitated with improved power integrity, while also providing EMI shielding along the edge of the circuit board.

For printed circuit board ('PCB') design, methods, systems, and apparatuses are disclosed. One apparatus includes a component ID module that identifies a PCB component to be placed on a current board design; a search module that displays one or more instances of previous board designs containing the identified PCB component, wherein displaying the one or more instances of previous board designs containing the identified PCB component comprises displaying a region surrounding the identified PCB component; and an import module that imports a selected portion of a board design into the current board design from a selected one of the instances of previous board designs containing the identified PCB component.

Printed circuit board design

A computer-implemented method according to one embodiment includes receiving log data from a component of a network, processing the log data to create processed log data, creating a component object, utilizing the processed log data, receiving an identification of a device connected to the network, determining a path within the network that is associated with the device, utilizing the component object, and returning the path.

Determining a storage network path utilizing log data

A controlled-impedance printed circuit board (PCB) design program allows interactive movement of features from one of the vertically-stacked layers of the design to another layer in a graphical interface. The movement either moves a region of a layer of the PCB design, or moves an entire layer in a layer-swapping operation. The program computes modified widths of circuit traces of the first layer of the controlled-impedance printed circuit board design according to an impedance control value of the controlled-impedance printed circuit board design and according to a new position of the circuit traces caused by a movement of the features of the first layer to the second layer. The program also checks for violation of reference plane requirements for critical signals and warns the designer if such a violation is present.

Controlled-impedance printed-circuit board (PCB) design with stack-up re-mapping

A child component ID module identifies child components connected to a parent component in response to selection of the parent component for placement on a PCB. The child components identified from component connections of a logic design. A child placement module places the child components around the parent component after placement of the parent component, where each child component is placed in compliance with constraints of the child components. A constraint highlight module identifies, on a PCB layout, an allowable area for component placement and prohibited areas for non-placement after selection of the component. The component is a parent component or a child component identified from component connections of a logic design of an electronic circuit design. The apparatus includes a constraint de-highlight module that removes identification on the PCB layout of the allowable area and the one or more prohibited areas in response to placement of the component.

Smart placement, visualization and optimization methodology for component placement and planning

Identifying and resolving issues with placement of plated through vias in voltage divider regions of a printed circuit board ('PCB') layout. Search parameters indicate an area of the PCB layout to be analyzed, and vias meeting the search parameters are evaluated for placement issues. Upon detecting a placement issue for a via, a solution is determined that addresses and resolves the placement issue of the via. The resolution in an embodiment includes modifying an adjacent power shape, modifying a region between shapes, and/or modifying via placement to minimize risks that include potential shorting, partially-connected vias, and/or poor plated barrel adhesion.

Dynamic electronic printed circuit board (PCB) design is provided. A test net on a PCB is dynamically created utilizing a first rule defining a net parameter and a second rule defining a padstack geometric parameter. A first evaluation of one or more nets having a first padstack is performed against the first rule. A second evaluation of both the first padstack and a reference padstack determined to be adjacently positioned to the first padstack is performed against the second rule. Based on the evaluations, a potential test net having a potential test padstack is dynamically selected from the evaluated nets. The selected potential test net is dynamically transformed into the test net. The dynamic transformation includes modifying the potential test padstack and/or the reference padstack utilizing the second rule. The dynamic creation of the test net improves the efficiency of electronic PCB design by mitigating time and footprint consumption.

A method, system and computer program product for dynamically sharing a limited supply of Internet Protocol (IP) addresses among a larger number of servers. A manager coupled between the Internet and a plurality of servers may receive a request for an IP address associated with a domain name from a client coupled to the Internet. The manager may be configured to map the domain name into an IP address assigned to the server hosting the web site of the domain name. Each assigned IP address may be valid only for a limited time. Once the time the assigned IP address is valid has expired, the assigned IP address may be returned to the pool of available IP addresses thereby allowing a smaller number of IP addresses to be dynamically shared among a larger number of servers.
